Enable caches for all Bazel commands, not just build-related ones.

Caching applies to all commands,
cf. https://bazel.build/versions/8.0.0/reference/command-line-reference#flag--disk_cache.

What are the commands that don't inherit from build? I'm reading and the docs and it looks like the common is not needed here because build is sufficient https://bazel.build/run/bazelrc:

• Every command inherits from common
• The following commands inherit from (and are more specific than) build: test, run, clean, mobile-install, info, print_action, config, cquery, and aquery
• coverage, fetch, and vendor inherit from test

Not 100% sure, but I guess something like bazel mod deps would not inherit from build and still make use of the repository cache.

Well, it won't hurt to use common, thanks for PR!

Thanks!
